Several laser-cooling methods, such as Doppler cooling and resolved sideband cooling, are used routinely to prepare controlled quantum states of atoms. Brennen de Neeve of the Swiss Federal Institute of Technology (ETH) Zurich and his colleagues now show just how efficient a laser-cooling process can be [3] (Fig. 1). They demonstrate a laser-cooling method that uses a \u201cspin-dependent force\u201d to transfer motional entropy from the atom into the entropy of its internal degrees of freedom.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new laser-based cooling scheme approaches the maximum efficiency that is theoretically achievable.
